Should I give it back?

OK so the other night I went to my new boyfriend's house and after we got out of the shower and ready to go to bed the said "you can use some of my underwear". now I don't know If I should give it back or keep it. I know I shouldn't have borrowed it but I did not want to look like a dirty mofo for using my dirty underwear.So what should I do?

Not sure why you said you should not have borrowed something he loaned to you during your overnight interlude at his house. Sometimes a guy will loan you a robe or shorts - even a suit if you're going swimming the next day. No problem at all........but I'd return them clean and folded. Next time he's at your house, you can offer him some of your shorts or a robe. Not a problem - in fact, I like seeing a hot guy at my breakfast bar the next day wearing something of mine!

He said you could "use" his underwear, not "have" his underwear. You will look like some kind of perv if you dont wash and return them.
